you'd be better off with something like
if(preg_match('#^[a-z0-9]+$#i', $GP['sifre'])) {
echo 'contains only alphanumeric chars';
} else {
echo 'contains characters which are not alphanumeric';
}- tul

I m trying to check $GP[sifre] variable, $GP[sifre] must consist of alpha numeric chars only. here, how I check the variable:
if((eregi("[^a-zA-Z0-9]",$GP[sifre]) echo 'true'; else echo 'false';
It works if variable starts with alphabetic chars only. for example this returns 'ok' $GP[sifre]='blabla234243'; but this does not work: (if variable starts with numeric chars) $GP[sifre]='3243242blabla';
second one returns false, couldnt figure out the problem here. any help ?
